• Do not allow foreign matter to enter the MCF. If rust, water droplets,
oil mist or dust from the pipe enters the device, measurement error,
control error, or damage may occur. Before installation, be sure to
flush upstream and downstream piping thoroughly to remove foreign
matter.
• Coat the pipe threads with an appropriate amount of sealant except for
the top two threads. Too much sealant might cause measurement error
or damage.
• When connecting a piping element such as a pipe with a different
diameter, a regulator, a filter, or a valve on the upstream side, use the
recommended straight pipe section. Failure to do so could cause a
measuring error.
• If a reducer or tube fitting is connected without a straight pipe section, the display might indicate a negative flow rate even though air is
flowing in the positive direction.
“Straight pipe section” refers to a straight pipe with the same diameter as the MCF port. The following types of pipe are suitable: Carbon
Steel Pipes for Ordinary Piping (JIS G3452), ANSI schedule 40 or
less; Carbon Steel Pipes for Pressure Service (JIS G3454), or ANSI
schedule 40 or less; Stainless Steel Pipes (JIS G3459).

• The MCF is a precision instrument. Do not drop it nor subject it to
shock.
• Install so that the direction of gas flow matches the arrow on the side
of the MCF.
• Do not apply force to the measurement module during installation.
• When attaching the MCF to the pipe, fix the MCF in place and rotate
the pipe to the recommended tightening torque.
● Filter
• If there is a possibility of foreign matter entering the device, install a
filter, strainer or mist trap upstream capable of eliminating foreign
matter larger than 1 µm in diameter.
● Accuracy and straight pipe length
• Connection with different size pipe, valve or filter
“Straight pipe section” refers to a straight pipe with the same
diameter as the MCF port. The following types of pipe are suitable:
Carbon Steel Pipes for Ordinary Piping (JIS G3452), ANSI schedule
40 or less; Carbon Steel Pipes for Pressure Service (JIS G3454), or
ANSI schedule 40 or less; Stainless Steel Pipes (JIS G3459).
If a device that is not listed in the table is installed either upstream or
downstream, contact Yamatake for the length of the straight pipe
section. If reverse flow is also expected, it is necessary to have the
same length of straight pipe downstream as upstream.

for Installation
Be sure to use this device within the flow rate range stated in the
specifications. To prevent excessive flow, use a suitable means to
control the supply pressure or use a throttle valve or the like to
control the flow rate.
• Although there are no restrictions of mounting direction, if the MCF
is mounted on a horizontal pipe and the display faces to the side, a
measuring error can be caused by the mounting direction.
Also, if the unit is mounted on a horizontal pipe with the display facing downward, foreign matter (rust, water droplets, oil mist, dust) in
the pipes might accumulate in the sensor, causing measuring error or
damage.
• Do not install this device near the outlet of a compressor or bellows
pipe, or in a location where the regulator or the check valve causes
hunting. Doing so could cause measurement error.

Note 1: Do not connect a carbon steel pipe for pressure service (JIS
G3454) or stainless steel pipe (JIS G3459) that is larger than
schedule 40. Doing so might cause a deterioration of
accuracy. (If the pipe schedule number is larger, the inner
pipe diameter is smaller, resulting in less accuracy.)
Note 2: The approximate size of the connection port (D) is 8 mm for
the MCF0080 (1/4 inch), 15 mm for the MCF0150/0151 (1/2

When connecting the MCF to a pipe 2 sizes larger than the
MCF port (for example, the MCF0080 to a 1/2 inch pipe), to
determine the straight pipe length use the section of the table
marked “Pipe one size larger in dia. (connected with reducer).”

Do not connect a smaller size pipe to the MCF without a
straight pipe section. Doing so might cause a reverse flow in
the measurement module, even though there is a regular
forward flow in the main flow path. Therefore the display might
indicate a negative value or an extremely low flow rate
compared with the actual rate.
When connecting the MCF to a pipe 2 sizes smaller than the
MFC port (for example, the MFC0150 to a 1/4 inch pipe), to
determine the straight pipe length use the section of the table
marked “Pipe one size smaller in dia. (connected with
reducer).” In addition, on the upstream side add 5D to the
straight pipe length.

• Before wiring the MCF, be sure to turn the power off.
• Connect a load with a resistance of not more than 300 Ω for the
instantaneous flow rate output.
• Keep water away from the cable and from the end of the connector while
wiring.
• Be sure to check that the wiring is correct before turning the power on.
Incorrect wiring could cause damage or malfunction.
• Power source ground, instantaneous flow rate output common, and event
output common lines are all connected inside this device. If these lines
are connected to an external device through a common power supply,
interference could occur causing device failure or faulty operation.
• Take care that the event output does not exceed the output rating of this
device. If a relay is used, the coil should have a built-in surge absorption
diode. Otherwise device failure could occur.

if the setting is zero, when there
is an alarm the output will be fixed
(unchanging).
• If the flow rate units are changed
in function setup C02, set Ao20
again.
The decimal point is not shown
in the setting range. Depending
on the model number the decimal
point is added to the display.
• Setup is enabled when function
setup C03 is set to 0 1 to 06.
• The decimal point is not shown in
the setting range. Depending
on the model number the decimal

again.
Settable in increments of 0.001. This
setting affects both indication and
output. If it is changed, the peak
value and lowest value for instantaneous flow rate are cleared.
This setting applies to both normal
flow and reverse flow.
The upper limit for indication can be
set at a lower level than the maximum of 200 %FS. If the flow
exceeds this upper limit, the display
will show only the value specified by
this setting.
Settable when function setup C03
is set to 07 to 10.

Flow rate
• If 4 mA flow rate ≥ 20 mA flow rate, the fixed output for alarm
occurrence is output.
• If the difference between the flow rate assignments for 20 mA and for
4 mA is smaller than the full-scale flow rate, the resulting lower
resolution may make it impossible to get the desired output.
* 2: Event output for instantaneous flow rate
Behavior depends on the setting in function setup C03.
(1) When C03 is set to 0 1 or 04 (instantaneous flow rate upper limit)
If the flow rate exceeds the instantaneous flow rate upper limit,
event output turns on. The point at which event output turns off
involves a hysteresis and is calculated as follows:
Event OFF point = instantaneous flow rate upper limit - hysteresis
Specify the hysteresis as a percentage of the full scale flow rate
(%FS).

(3) When C03 is set to 03 or 06 (within range for instantaneous flow
rate)
When E1.SP > E2.SP, the setting for E1.SP is used as the upper
limit and the setting for E2.SP is used as the lower limit. When
E1.SP < E2.SP, the E1.SP setting is the lower limit and E2.SP
setting is the upper limit.
When E1.SP = E2.SP, this function does not operate.
Hysteresis should be set below the lower limit and above the upper
limit. Specify hysteresis as a percentage of full scale flow rate
(%FS). Different hysteresis can be set for the lower limit and the
upper limit.

Remedy
Check that the supplied power and polarity are correct.
Check that the connector is connected correctly.
Check for air leaks
Check that wiring is correct.
When the MCF is mounted on a horizontal pipe and the display unit
faces the side, zero point drift may be caused by the mounting direction. Set the low flow cutoff to 5 %FS.
If the MCF is mounted where the ambient temperature or the temperature of the measured gas fluctuates widely, the MCF
might detect convection inside the pipe as a flow. Try measuring after the temperature stabilizes.
Check for air leaks.
Check if foreign matter is stuck on the main path orifices. If so, remove it.
After detaching the measurement module from the main path, check if foreign matter is stuck on the main path orifices. If
so, blow it off with compressed air.
After detaching the measurement module from the main path, check if the internal filter is stained. If so, clean it.
Check if foreign substances such as dust or oil are present on the pipe or the connection port of the MCF. If so, ask
Yamatake for repair.
Check that the wiring is correct.
Check if the flow fluctuates widely, or if it greatly exceeds the measurable limit.

If the setting exceeds the upper limit for indication, the instantaneous
flow rate output will be equivalent to the upper limit for indication.
Do not set values for Event 1 instantaneous flow rate or Event 2
instantaneous flow rate that exceed the upper limit for indication. The
instantaneous flow rate may not reach the set value, so that the event
does not operate.

Remedy
Check for excessive flow. If a minus sign is shown on the flow rate display
when the alarm occurs, there might be a reverse flow. Correct the factor
causing the reverse flow.
When the actual flow enters the normal range, the alarm lamp should turn off.
Set the correct flow path identifiers in maintenance mode. If the MCF does
not return to normal after the setting is changed, reboot it. If the MCF does
not return to normal after being restarted, call for repair.
If the MCF does not return to normal after rebooting, call for repair.
If the cause of this alarm is excessive reverse flow, the MCF will return to
normal automatically when the flow falls within the measurable range.
If the alarm does not turn off in spite of a normal reverse flow, ask for repair.
If the MCF does not return to normal after a few hours of dry air flow, call for
repair.
If the MCF does not return to normal after a few hours, call for repair.
